UCB BR18-SH4Q Smart Light Bulb: Bluetooth connected, supports Alexa and BRmesh APP control
Ever wished your lights could just... get you? These LED bulbs are here to make that happen, no WiFi required—just Bluetooth. Whether you're team Alexa or prefer the BRmesh APP, you've got full control. Fancy a cozy warm glow or need to simulate high noon in your living room? Adjust the color temperature from 2700K to 6000K and dial the brightness up or down from a whisper (1%) to a shout (100%).
Talk about hands-free living. These bulbs play nice with Alexa (sorry, 1st Gen Echo and Dot, you're left out of the party). Just say the word, and your lights will obey—no need to even glance at a switch.
Here's the kicker: these bulbs dim smoother than a jazz singer, with zero flicker to ruin the vibe. And with Bluetooth 5.0, you can command a small army of up to 100 bulbs. Perfect for when you decide your entire home needs a lighting makeover.
Inside the box, you'll find 4 smart bulbs and a user manual (because even smart lights need a little introduction). Ready to light up your life the smart way?
